Answer: First, you need to get the 6% of $95 which would be: $5.70. Then you need to multiply $5.70 to 11 to know how much of the 6% of $95 will be added at the end of 11 years. It will leave you with $62.70. Since you're adding $18 per year, you need to multiply it by 11 which would be $198. Now that you calculated all the money you will be having at the end of 11 years, you just need to add them all up. Since you have already $95 + $62.70 + $198 = $355.70. The total money you will be having is $355.70.

Prove the divisibility of the following numbers:

24^54·54^24·2^10 by 72^63

Factorize each composite base:

Then

Now cancel as many factors as possible:

The denominator vanishes, so does divide .

The sum of two consecutive odd integers is 128. find the two integers.

Call the first odd number x.

That means the next odd number would be x+2.

For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay?

So then, x+x+2=128

2x+2=128

2x=126

x=63

x+2=65

Thus, the two consecutive odd numbers are 63 and 65.

Hope I helped :)

That means the next odd number would be x+2.

For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay?

So then, x+x+2=128

2x+2=128

2x=126

x=63

x+2=65

Thus, the two consecutive odd numbers are 63 and 65.

Let's make an equation where y is the largest number.

x+y=128

Since odd consecutive numbers are two away, we can make an equation for y.

x+2=y; let's plug that in for y in the first equation.

x+x+2=128; let's add like terms.

2x+2=128; let's subtract 2.

2x=126; let's divide.

126÷2=63=x

If x is 63, y is 65.

So the two numbers are 63 and 65.

x+y=128

Since odd consecutive numbers are two away, we can make an equation for y.

x+2=y; let's plug that in for y in the first equation.

x+x+2=128; let's add like terms.

2x+2=128; let's subtract 2.

2x=126; let's divide.

126÷2=63=x

If x is 63, y is 65.

So the two numbers are 63 and 65.

Seven more than the product of a number and 8 equals 2 Use the variable w for the unknown number

Answer: w • 8 + 7 = 2

Step-by-step explanation:

Just translate the words into numbers. Product is multiplication and seven more means add.

Answer:

Equation:

(W * 8) + 7 = 2

W = - 0.625

Step-by-step explanation:

8W = - 5

W = - 0.625

Sherry has an after-school job at Papa John's. Her boss keeps track of how many pizzas she sells each day. During her last five days of work, she served 29, 58, 15, 75, and 22 pizzas. What was the mean number of Pizzas Sherry Sold?

What was the mean absolute deviation of the pizzas she sold?

I can partially answer that:

mean is: 39.8

because you find the mean by adding up all numbers and divide by number of digits. Hope I helped!
